Particle size distribution by laser diffraction (dispersions)

Determination of particle size distribution (PSD) by Laser Diffraction (LD). Analysis can be performed on dispersions or solids that can be dispersed in water or organic solvents. The method can analyze particle sizes from 0.010 µm to 2000 µm.

The test report will include a particle size distribution graph, values for volumetric mean = D[4,3], and the following percent finers (percent finers represent the amount of the material from the sample that is smaller than a certain size):

• Dv(10) / D(v,0.1) / 10 %

• Dv(25) / D(v,0.25) / 25 %

• Dv(50) / D(v,0.5) / 50 % = median

• Dv(75) / D(v,0.75) / 75 %

• Dv(90) / D(v,0.9) / 90 %
